The myth propagated by dumb people is that campaigns would focus solely on big cities like NYC and LA even though urban populations account for what, 20-25% of the nation? I'm just making that number up but it can't be as much as people think.
But what would the real strategies be? It'd be much more exciting to see Democrats campaigning in Texas and Republicans campaigning in New York than the same old Ohio and Florida visits.
Would Democrats really spend that much time campaigning in the most Republican areas and vice versa? Or would it be more cost effective to spend most of your time trying to drive up the turnout in your own base regions?
Sure, but think of the campaign. A Democrat in DC or Republican in Utah has less need to vote because they already know how their state is voting. In a close race, the election is decided by several thousand swing voters in FL, VA, OH etc. Now you have campaigns where every vote counts, so there's way more incentive to hit up your base like crazy than trying to pick up swing voters who aren't that dedicated to the process anyway.
